On May 17th the Canada Wood Japan team visited with major Japanese home builder Ichijo Komuten at a construction site to witness the first use of the Midply shear wall in a residential application in greater Tokyo area. The Canada Wood technical team has been in discussion with Ichijo Komuten for approximately 3 years to assist in the technical development and broader market adoption of Midply in Japan. The first residential use of Midply is in a 115m2 two storey 2×4 home in Koshigaya Laketown in Saitama Prefecture. The builder adopted the use of Midply in a new line of high performance homes to deliver the next generation of seismic performance in 2×4 construction. The Midply walls consist of SPF dimension lumber and OSB structural panels that are used extensively on the first and second floors. This use of Midply allows for the homes to substantively exceed the seismic performance of even the top class of Rank 3 homes currently designed under Japan’s Housing Performance Labelling Index. Midply is an open source Canadian building innovation developed by FP Innovations and UBC. Canada Wood Japan is broadly promoting Midply in Japan as the next generation seismic building solution.
